Determining colour from

Ashiataka

Suppose I have a picture of a flame, or some other blackish-body like emitter, and I can see that the RGB value of a part of the flame is [106, 216, 177]. How would I go about determining the temperature of this?

I'm sure you'd use Wien's law etc, but I can't see how to get from the RGB value to the frequency.

Thank you.
